Project Xpedit : Device for Hiking and Trekking

When you are planning to do an adventure journey or trekking to the wild, it is essential to have a device in your backpack that helps you to understand the environment. For my upcoming adventure journey, i planned to build a device that helps me to monitors temperature, humidity, air pressure, and altitude.

@Suhailjr When you post project details, please try to include a picture and basic technical information will be better for understating.
I haven't found a good sensor module for this at al
another option is that you can build capacitive sensor your own with resistors.

Have you ever wondered what the future of energy would be like? Especially since machine learning has opened up such a wide range of innovations and opportunities?
Care to take a look at the answers?
The RSET IEEE Power and Energy Society SBC proudly presents to you an informative webinar on "Machine Learning in Power Systems" hosted by Dr. Qiuhua Huang.
Dr. Qiuhua Huang is currently a Senior Power System Research Engineer with the Electricity Infrastructure Group, Pacific Northwest National Laboratory, USA. He has been a Principal Investigator, Project Manager, Task Lead and Key Technical Contributor in 10+ DOE-funded projects. Besides these, he is also the recipient of the 2019 IEEE PES Prize Paper Award, 2018 R&D 100 Award and several other achievements in his field of expertise.
Join us as we delve into the enigma that is Machine Learning.

@salmanfaris best if you could point me to an example that works as described: getting different values depending on hoe close the finger is without really touching. nothing i tried did work yet
@salmanfaris I haven't found a good sensor module for this at all. I used a thing which was calles touch sensor and it returns only 1/0. Tried to use touchRead() but it is not sensitive apparently, only 40 and 1 more or less.
#define touch_pin_numer 33
const int VALUE_THRESHOLD = 30;
TOUCH_SENSOR_VALUE = touchRead(touch_pin_numer);
if(TOUCH_SENSOR_VALUE < VALUE_THRESHOLD)
Serial.println ("Touch ON");
Serial.println ("Touch OFF");
should show something between 40 (current max) and 1 (current min) the closer the finger gets but it shows 40/41/39 and 1 - nothing inbetween. got this code from the web
